Front Pads - Dual Duty - Well the nearest I have found so far is the Project Mu HC+ (Titan Kai) which have a temperature range of 0～800 C (0-1472 F ) They work reasonalbly well with my very Aggressive driving style ...EXCEPT at one track that is notoriously hard on brakes, where they went a bit soft.
What fluid are you running ? ... I cooked my ATE ... but my Pentosin has been holding up much better (Similar to RBF600) to the track days. I will be switching over to SRF I think.
Both Sides have some clearance issues for the 3" brake duct ... Left side has the Intake resonator, which is easily removed, and the Right side has the washer fluid bottle, not so easily removed, however there is some space between the under tray to squeeze it thru, beside teh washer bottle. The Fog Lights will have to be sacrificed for an inlet (Allready done), and the only real issue will be running the ducts to custom backing plates on the knuckles. That is next on my to do list.
I have heard that the TL-S brakes will work, but I have not been able to track down if it is a bolt-up type application ... I would personaly only use Honda/Acura applications caliper / rotors, just because of potential hub-bore clearance issues ... that being said there is allways a way around the issues.
In terms of potential OTS Front Big Brake kits ... Brian Hasty at Fast Brakes has a 13" Willwood caliper option with a full floating 2 peice rotor that should be close to OE specs in terms of maintaining the F/R bias. Rotora's 4 piston Caliper upgrade also is close to OE in spec using the OE rotor, with a bit more front bias. His stuff is well designed and engineered and is resonably priced.
The biggest problem with the Si's Front brakes is the Weight of the car ... I am not convinced that there is a dual duty pad that will work well enough at the track ... I could get away with a Dual Duty pad on my 93 Civic Hatch ... mainly because it was light at ~2100#.
Changing pads and rotors at the track is fast ... about 15 minutes a side, and I have the rims off anyways to change over to the track setup anways.

-Cooling ducts: Has anyone tried this before? The space looks a little tight on the passenger side for routing a duct. What about the intake duct? I am a little concerned the intake and/or ducting my not last long for a daily driver.
-Acura TL Type-s: Are the 12.3 rotor and Brembo caliper a direct bolt on to a 2006+ Si?
-Calipers: I am looking for calipers with the correct piston size that could fit a larger rotor. Radial mount is much easier to make a bracket for. I am considering only OEM or Brembo and Stoptech if I found the right ones. I don't want to spend $3k+ on a big brake kit. I also prefer to be able to get parts from a local auto shop rather than need to special order replacement/repair parts. Other than good pads that is.
1) Acura RL - Anyone know the caliper piston diameters? Downside is it looks like only EBC (no good for the track) and Carbotech make pads for the 05+ RL.
2) Saleen has a 40/36mm (2274 mm^2) Brembo radial mount that would be easy to make a bracket for but is rare and if found, likely pricey.
3) The other caliper I found specs for is the Porsche 944 S2 (non M030 sport suspension whatever that is) and 87+ 944 turbo. They are also 40/36mm Brembo but am unsure if they are radial mount.
-Possible larger 5x114.3 rotors are 02-05 STI 12.7" x 30mm, 06-07 IS350 13.15" x 30mm, 05 G35 sedan 12.6" x 28mm, Mazdaspeed6 12.6" x 25.4mm and 08 STI 12.8 x 30mm. A larger diameter and/or 28-30 mm thickness would also add more thermal capacity and surface area to dissapate heat.
-Adapter bracket for the stock caliper to fit a larger rotor: I saw the Powerslot Plus kit but it uses a 14" rotor which would more than likely be way too much front bias without doing something to rear. The rear is more than ample so I see no need to mess with it. I sketched a bracket for a 12.5" ish rotor and can't come up with a good bracket design. Anyone else tried?
